I encourage the pure Scheme approach.  I recently made the switch to  
(planet jaz/mysql:1:4) because "it just works."  For several years  
I've used C & FFI to talk to MySQL (David Van Horn's perfectly good  
package) , but I recently got burned when I got a new Mac, reinstalled  
MySQL, found out it had a 64-bit library, while my C/FFI interface was  
32-bit.  The problem was, I needed to be up again quickly, so I  
converted my client code to use the fairly new and very usable jaz/ 
mysql PLaneT package.  I can talk to my database again.  I'll look  
again at the 64- and 32-bit issues when I'm less pressed for time.
